Hi, something strange has been happening the past two days. Yesterday, my iPhone and wireless printer required me to re-enter the password to connect to the wifi router. After I re-entered that for the printer, no problem. However, iPhone keeps losing connection. Even I entered the correct password, sometimes it says that my password is incorrect. Other times it says that it cannot connect to the network. Sometimes connected for 1-2 second and then disconnected again. MBP happened once today but after I re-entered the password, it connects without issue. What is happening?
